、光によって変色し美観を損ねる。(Prior Art) In structures using materials such as bricks and tiles, joints are used to join the materials together. Generally, joints are made of the same quality as the materials being joined.
For example, joints of the same quality as brick are used for brick structures, refractory mortar is used for fire-resistant brick structures, and ordinary cement mortar is used for structures such as red brick construction. In recent years, tiles have been widely used on the interior walls of bathrooms, toilets, and other places, and as joints, cement mortar-based materials containing silica, calcium oxide, calcium carbonate, etc., or organic resin-based materials containing silicone, etc. etc. are being used. However, in places with poor air circulation, high temperature, and high humidity, mold tends to grow in the joints. Mold is particularly likely to grow in the joints of bathrooms, spoiling the aesthetic appearance of walls and being unfavorable from a sanitary standpoint. However, mold that has grown is difficult to remove easily. For this reason, various antifungal agents such as organic phosphoric acid compounds, organic tin compounds, tetrachloroisophthalonitrile compounds, and henzimidazole compounds have been used in joint fillers. It is difficult to homogeneously mix these anti-mold agents into the joint material when heated, the effectiveness varies depending on the type of mold, there are problems with the sustainability of the effect, safety, etc., and the color changes due to light and the aesthetic appearance is affected. damage.

。(Means and effects for solving the problems) In order to solve the above problems, the present invention proposes a joint material in which an antibacterial calcium phosphate compound is added to a conventionally used joint material. The antibacterial calcium phosphate compound added to the joint material can be easily synthesized as follows. That is, a calcium phosphate compound selected from tricalcium phosphate and hydroxyapatite is added to an aqueous solution of a salt of at least one metal selected from silver, copper, and zinc, which has antibacterial properties, and the mixture is sufficiently heated if necessary. Stir. After stirring, the precipitate is collected, thoroughly washed with water and dried, or the precipitate obtained is mixed with water-soluble salts of these metals in the process of synthesizing calcium phosphate compounds from phosphates and calcium salts using a conventional method. The precipitate obtained by collecting, thoroughly washing with water and drying, etc. is calcined at a high temperature, preferably 800° C. or higher, and the calcined product is pulverized to obtain an antibacterial calcium phosphate compound. Hydroxyapatite is Cato(Po4)h(
It is known that it has the composition OR)z and has excellent adsorption and ion exchange ability, but Ca/P = 10
The synthesis of calcium salts and phosphate salts of compounds having a stoichiometric molar ratio of /6 is complicated and difficult. However, hydroxyapatite mixtures with a molar ratio of Ca/P = 1.4-1.8 are more easily synthesized with calcium salts and phosphates, and such hydroxyapatite mixtures can also be used in the same way as hydroxyapatite. The term hydroxyapatite in the present invention also includes such mixtures. The type of antibacterial metal to be supported on the calcium phosphate compound can be easily selected depending on the type and concentration of the metal salt used, and can be changed arbitrarily within the saturated adsorption or ion exchange amount, but it can be used by incorporating it into the joint material. Due to the problem of discoloration when using calcium phosphate compounds,
It can be said that 0.01 to 15% by weight is preferable. In addition, the amount of antibacterial calcium phosphate compound added to the joint material is 0.001 to 5% by weight relative to the joint material due to its antifungal effect.
It is blended in a proportion of 0%, preferably 0.01 to 30%.

粉砕してえたものである。Considering the treatment method, the antibacterial calcium phosphate compound added to the joint material is an antibacterial calcium phosphate compound because the antibacterial metal is supported on the carrier calcium phosphate compound by adsorption or ion exchange and then fired. The compound shrinks, and the bond between the supported metal and the calcium phosphate compound that is the carrier is strengthened. Therefore, even if the antibacterial calcium phosphate compound is treated with water, the antibacterial metal will not be leached into the water, and therefore the antibacterial effect of the joint material containing it will be maintained and it can be used safely without deterioration. . In addition, since the antibacterial calcium phosphate compound has similar properties to the joint material, it was easy to mix with the joint material and a uniform dispersion was obtained. It is easy to imagine that moldy joint materials could be replaced. The antibacterial calcium phosphate compounds used in the experiments were prepared by adding the calcium phosphate compounds to an aqueous solution of silver nitrate, copper nitrate, zinc nitrate, or a mixture thereof, stirring thoroughly at room temperature, collecting the precipitate, washing with water, drying, and adding 1000 It is obtained by firing at ℃ and finely pulverizing it.
